Abstract: For the manufacture of acetylene and synthesis or reduction gas from coal by means of an electric arc or plasma process, coal converted into powder form is pyrolyzed in an electric arc reactor with an energy density of 1 to 5 kWh/Nm3, a residence period of 0.5 to 10 msec and at a temperature of at least 1500 DEG  C. such that the gaseous compounds derived from the coal do not exceed 1.8 times the so-called volatile content of the coal. The coke remaining after subsequent quenching is then fed to a second electric arc reactor in which the coke, by means of a gasifying medium in conjunction with heating by means of an electric arc or plasma process, is converted into synthesis or reduction gas furing a residence period of 1 to 15 sec and at a temperature of at least 800 DEG  C. The gas flow from the pyrolysis zone is cleaned and acetylene is recovered therefrom by selective solvents. The gas from the cleaning stage is similarly cooled and cleaned.

Abstract: A torque wrench having a shaft with a tool head at one end a handle at the other end. The handle is supported on a lever system having a first and a second two-armed lever. One arm of the first lever engages one arm of the second lever. The handle is supported at two points on the other arm of the first lever and the other arm of the second lever. The other arm of the first lever engages a force sensor, which is attached to the shaft. The levers are dimensioned such that the measuring force acting upon the force sensor, when an applied force acts on the handle, is independent of the point of application of the applied force and is always proportional to the torque exerted about the axis of rotation of a tool.

Abstract: This invention relates to a base structure for a switch cabinet having in combination four corner sections, at least two transverse panels and at least two longitudinal panels. The corner sections have two vertical outer walls joined at right angles and the ends of the outer walls are bent inwardly to form mounting flanges provided with mounting holes. The top and bottom of the corner sections have cabinet mounting flanges with mounting holes. Transverse panels and longitudinal panels are screw-fastened to the corner section mounting flanges so their outer surfaces are flush with the outer surfaces of the corner sections. Corner sections, transverse panels and longitudinal panels are adapted to be assembled and disassembled from the interior of the base structure. This base structure configuration ensures that any panel may be removed from bases upon which switch cabinets are mounted in rows of cabinets, and reinstalled without moving the switch cabinets.

Abstract: For energizing a load (10) with different input voltages, the circuit comprises a transformer (6), whose primary winding (n1), in series with the collector-emitter path of a switching transistor (T1), the load (10), and a current sensing resistor (R2), is arranged between the input-voltage terminals. The seccondary winding (n2), in series with a diode (D1), is arranged in parallel with the load (10). When the input voltage is applied a very small base current is fed to the switching transistor (T1) via the starting resistor (R1), which results in a small current in the primary winding. The resulting voltage rise across the secondary winding (n2) ensures that the switching transistor (T1) is bottomed rapidly via a positive-feedback loop, which comprises the series arrangement of a first resistor (R4), a capacitor (C1) and a second resistor (R5) and which is arranged between that end of the secondary winding (n2) which is connected to the diode (D1) and the base of the switching transistor (T1). For a specific current in the primary winding (n2) the switching transistor (T1) is turned off by means of a control transistor (T2), whose base is connected to the current-sen sing resistor (R2). The energy stored in the transformer (6) is then delivered to the load (10) by an output current in the secondary winding (n2). In order to prevent this output current from increasing strongly at increasing input voltages as a result of the increasing saturation of the switching transistor (T1) via the positive feedback, a zener diode (Z1) is arranged between the junction point of the capacitor (C1) and the resistor (R5) and the base of the switching transistor (T1). Above a specific input voltage this zener diode (Z1) is turned on and drains the base supply current to the emitter of the switching transistor.

Abstract: A drilling bit, such as a crenellated drilling bit for fluid-jet supported rotary drilling in rock comprises a nozzle for directing a jet of high-pressure fluid against rock material being bored. In addition to transporting away rock chips, the jet penetrates fissures in the rock and supports the breaking down of the rock structure by the drilling bit. Since such nozzles tend to wear more rapidly than the cutting edges of the drilling bit, a readily exchangeable nozzle insert is provided. The nozzle insert is seated in a retaining body incorporated in the drilling bit and is held in the retaining body by a threaded annular cap. The annular cap has a hexagonal recess for accommodating a tool such as an Allan-key.

Abstract: A method for maintaining a stable liquid level in a pressurized chamber is described. According to this method a liquid to be treated is heated by direct contact with steam with the consequential condensate being mixed with the treated liquid and removed from said chamber. The following steps are provided: establishing a desired flow rate of liquid to be treated into said chamber, supplying saturated steam to said chamber to heat said liquid by contact heating to condense the steam, collecting the treated liquid along with the condensed water from the steam to maintain a predetermined liquid level in said chamber, varying the rate of steam supply and pressure to maintain the predetermined treatment temperature of the liquid as it is removed from the chamber, and selecting and using for each liquid to be treated a fixed flow area device (276) to control the rate of removal of said treated liquid from said chamber to maintain said predetermined liquid level irrespective of variation of control and said steam supply. An advantageous application field of this method is a process for heating fluids to a relatively high temperature, such as sterilization of UHT temperature, in which the liquid is heated by direct contact with steam while it is held in the form of a very thin, free-falling or a continuous falling stream.

Abstract: A computing system uses a system busy signal (SDBUSY) on its system bus to help control access to the bus. Each requester requiring access to the bus generates its internal request signal (SET REQ). One or more requesters can generate a request signal (SDREQX) on the bus when the system busy signal is not asserted (gate 74 and flip-flop 76). System busy is asserted along with the request signal(s) and remains asserted until all requesters which generated a request signal have gained access to the bus in order of priority. Bus access is enabled by a signal (PRIORITY) only when all higher priority request signals (SDREQ1-SDREQX-1) are false (gate 72). A freeze signal (DRVFREZ) is generated on the system bus during the address phase of an instruction and a wait signal is generated during each data transfer in the data phase of an instruction. These signals must be false before a requester with its request signal and priority signal tone can access the bus by putting an address signal thereon. The freeze signal may be generated by a memory control unit, a memory module or a requester.

The safety band overlays approximately half the perimeter of the cap and its height is generally the same as that of the cap itself. In this way, the cap cannot be grasped in the area opposite the hinge, and thus cannot be opened. A lug may additionally be provided on the cap which is engageable in a corresponding recess in the safety band to provide the closure in a closed and sealed condition, thus holding the closure and preventing it from opening under the effect of excess pressure in the container.

Abstract: To avoid friction losses or the striking of a sealing part (1) against the edge of a sealing surface interruption, the movement of the sealing part (1) into and out of contact with the sealing surface is controlled by the medium to be sealed, so that there is a sealing contact only at that moment in which there is an overpressure in the area to be sealed. This control takes place through the vacuum produced in the sealing gap (8) during the brief flow therethrough and the relative overpressure with respect thereto on the opposite side (10) of the sealing part (1). In the differential pressure-less state, the sealing part is e.g. held by a spring (6) at a distance from sealing surface (5).
